	operator handle_type () const
	Auto-typecasting operator.

handle_type *&	operator* () const
	Returns the object handle value when the object handle is a pointer to a value (class, struct, etc.).

handle_type *	operator& ()
	Returns the object handle reference.

handle_type	operator-> () const
	Provides object handle member access when the object handle is a pointer to a class or struct.

bool	operator! () const
	Tests if the object handle is invalid.

bool	operator< (handle_type h) const
	Is handle less than?

bool	operator<= (handle_type h) const

Protected Member Functions
virtual handle_type	duplicate_internal (handle_type h) const =0
	Abstract member function that must be implemented by child classes to do the actual object handle duplication. On failure, it should throw appropriate exception describing the cause, rather than return an invalid handle.

Constructor & Destructor Documentation

◆ dplhandle() [1/3]

template<class T , T INVAL>

winstd::dplhandle< T, INVAL >::dplhandle ( handle_type h )

inlinenoexcept

Initializes a new class instance with an already available object handle.

Parameters

[in] h Initial object handle value

◆ dplhandle() [2/3]

template<class T , T INVAL>

winstd::dplhandle< T, INVAL >::dplhandle ( const dplhandle< handle_type, INVAL > & h )

inline

Copy constructor.

Parameters

[in,out] h A reference of another object

◆ dplhandle() [3/3]

template<class T , T INVAL>

winstd::dplhandle< T, INVAL >::dplhandle ( dplhandle< handle_type, INVAL > && h )

inlinenoexcept

Move constructor.

Parameters

[in,out] h A rvalue reference of another object

Member Function Documentation

◆ attach_duplicated()

template<class T , T INVAL>

void winstd::dplhandle< T, INVAL >::attach_duplicated ( handle_type h )

inline

Duplicates an object handle and sets a new object handle.

Parameters

[in] h Object handle of existing object

◆ duplicate()

template<class T , T INVAL>

handle_type winstd::dplhandle< T, INVAL >::duplicate ( ) const

inline

Duplicates and returns a new object handle.

Returns: Duplicated object handle

◆ duplicate_internal()

template<class T , T INVAL>

virtual handle_type winstd::dplhandle< T, INVAL >::duplicate_internal ( handle_type h ) const
